Recent advances in our understanding of cyanobacterial photoacclimation have the potential to improve photosynthetic efficiency in crops. Whereas oxygenic photosynthesis typically relies on visible light, some cyanobacteria acclimate to absorb far-red light, thus expanding the absorbance cross-section of their photosystems. This expanded absorbance range, via the implementation of red-shifted chromophores, could be bioengineered into crops to enhance yields by capturing more light energy and boosting photosynthetic efficiency in light-limited environments. Recent insight into natural cyanobacterial photoacclimation mechanisms offer promising avenues for engineered photosynthetic improvements in agriculture.
我们对蓝藻光适应的最新认识进展有潜力提高作物的光合效率。虽然有氧光合作用通常依赖可见光,但一些蓝藻会适应吸收远红光,从而扩大其光系统的吸收截面。通过引入红移发色团实现的这种扩大的吸收范围,可以通过生物工程手段引入作物中,以在光照有限的环境中捕获更多光能并提高光合效率,从而提高产量。最近对天然蓝藻光适应机制的深入了解为农业中通过工程手段改善光合作用提供了有前景的途径。
